Advanced gastric cancer cases (42 cases) undergone gastrectomy were studied on the correlation between tissue uptakes and prognosis. The patients were administrated Tegafur preoperatively and tissue samples were obtained intraoperatively, 5-FU levels in tumor and lymph node were measured by GCMF. The patients, being measured 5-FU uptake by tissue and received Tegafur over 60 g as postoperative adjuvant chemotherapy, were divided into two groups; namely, one with 5-FU up take by tumor tissue and lymph node was higher than 0.05 mcg/g and the other with lower than 0.05 mcg/g. Both groups showed no significant difference in background factors. Each survival rate was calculated by Kaplan-Meier method and examined by generalized Wilcoxon method. As the result, there was no significant correlation in the 5-FU uptake by tumor and prognosis, but prolongation of survival rate in the group of 5-FU uptake by lymph node over 0.05 mcg/g was suggested.
